I think the biggest three things I require out of my partners is honesty, love, and respect!
If they both have honesty, love, and respect for me each other and all the people that come in and out of our family than nothing else matters. If at anytime one of us don't feel one of these things than we must be brave enough to talk about it. If we can't talk about it than where is the honesty, where is the hope for things to get better. Besides these three thing I think trusting the ones you are with is importing. Trusting them to the point that they will keep these three values in mind/heart and that any thing else they do, in addition to some level of personal responicibility, is fine (and there own buissness) I liked the first responce given... pay the bills and do what ever.I'm not quite so simple but close
